Absolutely can not recommend this lovely apartment due to the proximity of two bars and the noise and heavy smoke that are directly outside your bedroom windows.
We stayed 4 nights here, Tue-Sat, 4 adults (in our 50's and 20's) with very liberal leanings who live in an urban setting in the USA. A warm week in June 2017.
The apartment interior is as advertised, a really nice place, comfortable and sizable. Pre-trip communication and checkin went smoothly. The general location in Mitte is excellent, close to many great bars and restaurants which we enjoyed. Also very convenient to many forms of mass transit.
When we booked we were aware of the bar downstairs but that "an understanding had been reached" to minimize noise. This was downplayed and assurances given at check in alos. And, in fact at midnight every evening the patrons of the bar went inside, BUT that hardly solved the problems with this location.
Each night around 8pm the street directly in front and below the windows of this apartment became filled with 25-50 young male patrons of the bar downstairs, drinking, talking and smoking a lot. It was warm, we opened the windows to cool off the place after a day out as there are no fans nor ac in the apartment, and in poured the smoke and the noise. Literally, there were men leaning against the cars and blowing cigarette smoke right toward the open bedroom windows, from 2 meters away, until midnight every night. The technopop continued until past 1 am each night, and the bar left their windows open. Every night we found young men hanging out on the doorstep to the apartment, especially on one raining evening, smoking and drinking and talking. Note, all the of the patrons were very nice, we never had any feelings of fear or intimidation or anything like that. Of course there were also many comings and goings and long goodbyes outside on the street until bar close. Additionally, a second bar, the Stein Keller, has just opened nextdoor (directly to right of door seen in photos) and they had tables out on the sidewalk until late hours, past 1am, their patrons not more than 4-5 meters from a bedroom window.
This is a great apartment in an excellent location cursed by the exceptionally close proximity of two bars and their patrons noise and smoke. We all like to party but we all agreed that this was just not okay as a rental. However, if you are a young gay man who drinks and smokes alot and loves techno pop until 1 am and later every night then you are in luck, this is your dream rental.
